FLUEI-CLEANER.

SPECIFICATION forming part of Letters Patent No. 589,590, dated September 7', 1897.

Application lecl May 5,1897. Serial No. 635,248. (No model-l To all wit/mz, ft ritrrf/ fro/werft,

Be it known that I, LOUIS J. W'OLF, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Iinprovelnents in Fluo-Cleaners; and I do hereby declare that the, following' description of ni y said invention7 taken in connection with the acooinpanjf'ing sheet of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the saine.

This invention has generalreference to iinproveinen ts in 'Iiuccleaners; and its object is to produce a tine-cleaner having a reoiproeating or vibrating hammer or chisel with means for automatically revolving the vibrator around the axis of the body of said flue-cleaner.

To this end the invention consists of the novel and peculiar combination of paris and details of construction, as hereinafter first fully set forth and described, and then pointed out in the claims.

In the drawings already referred to, which serve to illustrate this invention more fully, Figure l is alongitudinal sectional elevation of my improved flue-cleaner. Fig. 2 is an elevation of the saine, parts being in section in line of Fig. l. Fig. 3 is a sectional plan in line y 3,/ of Fig. l. Fig. 4 is a sectional elevation of a fragment of the device in line ,e e' of Fig. 3. Fig. 5 isasectional ele vation of the lower portion of the body and illustrating a modified form of connection of `fthe steam-pipe with the body of the cleaner.

Lilie parts are designated by eorrespondin g letters of reference in all the figures.

A A are tivo cylindrical shells screwed together at d and constituting the body of this flue-cleaner. rIhe lower part A terminates in a hell B, having a hexagonal ivrench-sec tion I3' for the application of a Wrench in conjunction with an aperture n" in the upper shell A for the reception et' the pin of a spanner-Wrench, by means of which the two parts A A may be securely fastened together; Below this Wrenchsection there is formed an externally screxvthreaded part B, upon which is located a clamping-nut C" and a. loclcnut 0"', which latter nut prevents the clamping-nut from revolving.

C is the steam, compressed-air, or Watersupply pipe. It terminates in a ball C', itting a correspondingly-shaped recess in the end of the part B and retained therein by the clamping-nut C", so as to forni a so-called ball-and-socket joint, which will enable the body of the cleaner to revolve on the said steam, the., pipe C and the latter to assume a position out of axial line with the said body, as Will hereinafter more fully appear.

In the interior of the lower shell A. there is formed a spider Il, above which is located a propeller-Wheel I, having centrally an upwardly-projecting boss I', provided with a projecting ball-shaped arin I", serving as a crank, and clearly illustrated in the figures.

The spider H has curved radially-arranged slots or passages 7i, pointing in a direction opposing that in which the siinilar radial slotsi in the propeller-Wheel areA arranged, and it has centrallyan aperture for the reception'of a stud K, upon which said propeller-Wheel revolves.

The upper shell of the bodyA is internally vbored out to receive a shell N, which is retained in position by a nut O screwed onto the shell A at its upper end. This' shell N has near its upper end a bridgeA, located to one side of the center of the said shell and adapted to receive the pivot o. of avibrating lever E, which lever is provided on its outer end with a hammer or chisel F and on its in- Wardly-projecting end 'or short arm with agrooved guide E", the groove of which en-4 gages the ball I" on the propeller-Wheel and thus converts the rotary movement of the said propeller-wheel into a reciprocating one of the said lever E. In the interior of this shell N there is formed an annular inwardlyprojecting ledge N', provided with a series of inclined slots n, the object of which will hereinafter be stated.

The bridge A has its members that connect the central hub with the body of the shell N inclined in opposite direction, as shown in Figs. l and 2, to coact with the inclined slots 'n in revolving the shell N Within the shell A by the escaping steam, dro., used to revolve the propellernvheel inipinging upon these inclincs.

In operation steam, compressed air, or \va ter under pressure enters the body of the lOO cleaner through the pipe C and, passing through the inclined or curved radial slots in the propeller-wheel., causes the latter to re.. volve and thereby the lever E to vibrate rap-y idly. In passing the cleaner through a watertube or boiler-flue it is necessary to revolve the same, so that the interior of these tubes may be thoroughly cleaned, and to so revolve the cleaner or a part thereof which carries the vibrating lever I pivot the said lever to the bridge located in the shell N, which, by the inclined slots in the inner annular-ledge, is caused to slowly revolve, it being assisted by the inclined surfaces of the bridge A. In this manner I accomplish the desired result in an efcient an eifective manner.

Instead of revolving the shell N within the shell A, I may discard this shell N and form the bridge A" integral with the shell A, forining the annular ledge in said shell A, or form radial slots h in the spider II and incline the same, as shown in Fig. 4, whereby the steam, dsc., passing through the body A A and acting upon the inclined surfaces yn and 7i, or either, causes the entire body to slowly re volve. In this case I need either of the two connections shown in the drawings to con neet the steam-pipe with the said body, preference being given to the ball-and-socket joint shown in Figs. l and 2, because the fluecleaner will be enabled to retain its position in axial line with the vflue or tube, though the stea1n-pipe C may be inclined thereto, which will happen when the apparatus is being introduced into the said tube or iiue to be cleaned.

In Fig. 5 I have shown the steam-pipe C attached to the body of the cleaner by a stuffing-box joint, which will be readily comprehended without further description and would be a substitute for the ball-and-socket joint shown in Figs. 1 and 2, though probably not quite so effective in operation.

IIavin g thus fully described my invention,

I claim as new and desire to secure to me by Letters Patent-of the United Statesl. In a iiuecleaner, a suitable body having a bell-shaped bottom, an externally-screwthreaded portion thereon, a clamping and a lock nut upon said screw-threaded portion, a supply-pipe having a ball on its end and engaging a recess in` the .end of said screwthreaded portion and held therein by said clamping-nut, an internally-projecting ledge in said body having a series of inclined slots or notches, a propellerwheel Within said body, a lever pivoted in said body and engaging said propeller-wheel with one end, and asuitable tool on the other end of said lever, whereby said lever is reciprocated and at the saine time caused to automatically revolve around the longitudinal axis of said bod y, as set forth.

2. A flue-cleaner consisting, essentially of a body composed of a lower section having a bell and a su ppl y-pipe connected therewith, a spider in said lower section, a propeller-wheel having a ball-shaped arm projecting therefrom, an upper section secured to said lower section, a spider in said upper section above said propeller-Wheel, a shell Within said upper section and retained therein by a nut on the end of the upper section, a ledge in said shell having a series of inclined notches or slots, a bridge in said shell, a lever pivoted to said bridge and connected with its lower end with said propeller-wheel, and a suitable cutting-coolen the outer end of said lever, whereby said lever is reciprocated and the said shell and lever caused toautomatically revolve within said body, as stated.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

LOUIS J. WOLF.
